Why is a kahoot locked? How can I unlock it?

If you’re an admin or a member of a team, you can edit and host other members’ kahoots. Only one person can edit a kahoot at a time. If needed, the kahoot’s creator or the team's admin can unlock a kahoot.

Simply use the three vertical dots to the right of the locked kahoot and select Unlock. This will end the current editor’s session, allowing others to edit it.
